How strong was a T. rex bite!?

[upbeat music] This episode is part of the Wild Critters U.S.A. series, a collaboration with Orb, PBS Nature, and the National Wildlife Federation.

[upbeat music] [dog barks] Hey, Hank.

Remember when you and I went to the American Museum of Natural History? [dog barks] Exactly.

The one with all the dinosaur bones.

I honestly can't stop thinking about all the dinosaurs.

Can you imagine what the world must have been like back then? [dog whines] Giant, long-necked dinosaurs eating the tops of trees.

[trees rustle] Massive crocodiles.

[crocodile growls] Giant flying dinosaurs.

[pterodactyl roars] Frogs croaking in the swamps.

[frogs croak] And of course, huge reptile monsters stomping around, shaking the ground with every step.

[dinosaur stomps] But the thing that really has my heart racing [dog barks] Exactly.

Turning around a corner and seeing a huge, hungry, I mean really ginormous T-Rex.

[T-Rex roars] That T-Rex fossil that we saw at the museum was enormous, taller than our house.

There's something I keep thinking about, though.

[dog barks] No, not the snacks we ate at the park after.

It was the T-Rex's arms.

They were really small, like ridiculously small compared to the rest of its body.

[dog barks] [upbeat music] I know, Hank.

It's not a good idea to make fun of apex predators.

I was just surprised.

I kept thinking, if that thing really tried to give me a high five, it probably couldn't even reach my hand.

[dog barks] So T-Rex was the most fearsome predator to ever live, and at the exact same time, the world's worst high-fiver.

But I wonder why its arms are like that.
